Check if the target environment meets AWS Gateway API migration prerequisites.

Args: lbc_version: AWS Load Balancer Controller version (e.g. "2.14.1"). Leave empty to skip. needs_l4: Set true if migration includes TCP/UDP/TLS routes (requires experimental channel). tls_hostnames: Comma-separated TLS hostnames to check ACM certificate coverage.

Analyze Nginx Ingress configuration and return a structured summary. Reports annotation compatibility, route type distribution, TLS hosts, cross-namespace refs, and cost estimate.

Args: ingress_yaml: Nginx Ingress YAML content (multi-document supported) or file path. tcp_services_yaml: Optional tcp-services ConfigMap YAML for L4 TCP routes. udp_services_yaml: Optional udp-services ConfigMap YAML for L4 UDP routes.

Convert Nginx Ingress YAML to AWS Gateway API resources (full pipeline).

Steps: base conversion → GatewayClass injection → TLS fixup → L4/L7 split → Gateway merge → LoadBalancerConfiguration → TargetGroupConfiguration → ListenerRuleConfiguration

Args: ingress_yaml: Nginx Ingress YAML content or file path. tcp_services_yaml: Optional tcp-services ConfigMap YAML for TCP routes. udp_services_yaml: Optional udp-services ConfigMap YAML for UDP routes. scheme: ALB scheme — "internet-facing" or "internal". namespace: Default namespace if not specified in resources. alb_gateway_class: Name for the ALB GatewayClass (default: aws-alb). nlb_gateway_class: Name for the NLB GatewayClass (default: aws-nlb). gateway_grouping: Gateway consolidation strategy: "by-class-scheme" (default) | "by-namespace" | "by-host" | "single" health_check_path: TargetGroupConfiguration health check path. health_check_interval: TargetGroupConfiguration health check interval seconds. healthy_threshold: TargetGroupConfiguration healthy threshold count. unhealthy_threshold: TargetGroupConfiguration unhealthy threshold count.

Generate a complete Markdown migration report. Includes: summary, cost impact, DNS changes, annotation analysis, health check reminders, ACM checklist, migration checklist, and rollback plan.

Args: ingress_yaml: Nginx Ingress YAML content or file path. tcp_services_yaml: Optional tcp-services ConfigMap YAML. udp_services_yaml: Optional udp-services ConfigMap YAML. scheme: ALB scheme — "internet-facing" or "internal". gateway_grouping: Gateway consolidation strategy. lbc_version: AWS LBC version for pre-flight checks (optional). health_check_path: TargetGroupConfiguration health check path. health_check_interval: TargetGroupConfiguration health check interval seconds. healthy_threshold: TargetGroupConfiguration healthy threshold count. unhealthy_threshold: TargetGroupConfiguration unhealthy threshold count.

Validate Gateway API YAML against schema rules and AWS LBC constraints. Checks: required fields, L4/L7 mixing, certificateRefs misuse, parentRef consistency, experimental channel requirements, and cross-namespace reference coverage.

Args: yaml_content: Gateway API YAML content to validate, or file path.
